i was jsut wondering kuz somone to me it wouldnt be bad to put karosene in ur bottom ned of your motor but i was wondering if it would be? Just a Question...

 

I have heard of this being done before. Although i never tried it for myself. Something about a quart of kerosene for a certain amount of time running then change the oil. I never been brave enough to try this myself though. This was for a car though. My dad has used a quart of transmission fluid in a full tank of gas before in his truck. They say it cleans out the injectors. It really helped his truck out amazingly enough. Perhaps kerosene is what they use when u take ur vehicle in for an engine flush. Wouldnt surprise me.

 

I have used Kero or diesel to flush a motor out. I would do this if your oil is really old and thick like sludge. I would only use it to flush the engine 5-10 minutes max.

DO NOT DO IT!!!!!!!! If you run such a strong cleaner like that you are taking a big chance! It would be fine on a new motor but of course who needs to clean a new motor. An old motor that needs cleaning likey from over due oil changes and or misfiring from poor tune ups, compression etc. should not do it because all of the bearing surfaces in your engine are also likely to be coated with gunk. The cam, crankshaft journals, rod bearing surfaces probable are worn and have gaps in the joints. What is keeping everything running quiet and from causing further damage is the baked on gunk in these wear joints. If your motor does have wear (only way to know is to pull the pan and bearing caps and measure the wear with plasti guage) and you clean it out with kero or any engine cleaner you will very possibly end up with bearing knocks in any possible place in the motor. Soon after you would get bearing failure. Throw a rod for instance. Especially if you had to do highway driving at moderate rpm's for any length of time. Then you will find yourself using STP and straight 50 wieght oil to nurse your knocks until you can get the engine rebuilt. Cleaning is not the answer. It is only a possible band-aid to a more sever lurking problem and it will either clean an ok amount or over clean it leaving your bearings loose throughout the engine. Can't repair the damage to and engine from lack of maintenance with a a quick fix such as cleaning. Now you may want to consider products that are designed to fill scratches etc. by simply adding them to your oil. Ask your autoparts stores about those products.
